This is the quiet advantage some families have passed down for years — adding their kids as authorized users so they start adult life with credit history already built. Here’s how it works, and how anyone can use it. (Starting completely from zero? How to Build Credit From Scratch.)
How it actually works
A credit card has a primary cardholder (whose account it is) and can add authorized users — people allowed to use the account. When the primary cardholder adds you:
- The issuer can report the whole account’s history to your credit report — including how old the account is and its payment record. (Issuers aren’t required to report authorized users and can change policy, so it’s not a given — which issuers do is below.)
- That history counts toward your credit age, payment history, and utilization.
So a parent’s 15-year-old card with on-time payments can give a credit newcomer years of "history" they didn’t have before.
How much does it actually help?
There’s no set number. How much your score moves — if at all — depends on the account’s age, credit limit, utilization, and spotless payment record, plus which bureaus the issuer reports to and the scoring model your lender uses. For some people the lift is meaningful; for others it’s small or nothing — anyone promising a specific number of points is overselling it. (For where any of these numbers actually land you, see what counts as a good credit score.) Use the card of someone you know and trust, not a "rented" spot on a stranger’s card (more on that below) — and per myFICO, in recent versions of the FICO Score authorized-user accounts have less impact than accounts in your own name.
What makes an account actually help
Not every authorized-user add helps — the account has to be a good one:
- Age: the older the account, the more it can raise your average account age.
- A spotless payment record: even one payment 30 days late on that account can show up on your report. ⚠️ It cuts both ways — a high balance or a missed payment on the primary’s card can hurt you, so only do this with someone responsible.
- Low utilization + a high limit: a card kept well under 10% of a high limit helps your numbers; a near-maxed card drags them down. (More on this lever: How Credit Utilization Works.)
- An issuer that reports AU activity: not every issuer does, so ask the issuer whether it reports authorized users. Some say so on their own pages (read October 20, 2026): Capital One says issuers "aren’t required to report an authorized user’s activity to the three major credit bureaus. Capital One does" (Capital One); Chase says it "provides account information to the credit reporting agencies for all account users" (Chase) but "does not report the authorized user credit history of minors" (Chase article); Citi’s card agreement says "We report information about this Account to Consumer Reporting Agencies in the Authorized User’s name" (Citi), and Bank of America’s says the account "may appear on any Authorized User’s consumer report" (Bank of America). American Express says it reports an Additional Card Member (its name for an authorized user) "when they are 18 or older" (Amex FAQ, read October 20, 2026). Reporting policies vary and change, so confirm with the specific issuer before relying on it.
How to set it up
- Ask a family member or trusted friend with a long, clean, low-balance card.
- They add you as an authorized user via the issuer’s app or phone line — they’ll need your name and date of birth, and some issuers also ask for an SSN or ITIN (it varies by issuer).
- That’s it. The history can appear on your report only after the issuer reports it to the credit bureaus, so ask the issuer first.
What to avoid
- Buying "tradelines." Services that sell authorized-user spots on strangers’ cards aren’t worth it. (The FTC has cracked down on it as a deceptive practice: in a 2020 case it said the seller couldn’t back up its score claims and charged $325 to $4,000 or more, and in a 2022 case it said a buyer of such a spot is an "authorized user" in name only, with no access to the account.) Use someone you actually know.
- Relying on it alone. Authorized-user history is a head start, not a finish line. Pair it with your own account — a secured card or a credit-builder — so you’re building credit in your own name too. (How those work: How Does a Secured Credit Card Work?.)
New to the US? This can work without an SSN — what an issuer asks for varies: Chase’s page mentions your name, address and date of birth, and American Express also asks for an SSN or ITIN (both read October 20, 2026), so ask the issuer first. See how to build credit as an immigrant.
The bottom line: being added as an authorized user on a strong, clean account is a possible head start, with no points promised: it can help when the account is the right one, and it works best alongside an account in your own name.
